Blow the balun on the F12 and you are out of action too.

The separate feedlines is an advantage if you need that kind of flexibility.
I have to wonder what all those extra elements do to the pattern.  What I do
know is the SteppIR just flat gets out.  Can they break sure.  Do they yep
and so does every other antenna out there.  Loose and element tip the
antenna should be coming down.  Yes you can still use the antenna but how
well? Rotors break in contests and rigs blow up too.  There are no
guarantees with electronics other then you if it is going to fail it will be
at the worst possible moment.  Murphy is really good at detecting that.  

Since the Computer blew up I guess you are back to paper logging?

The list of things that can go wrong is nearly limitless.

If SteppIR announces what we thing they are at Dayton.  You will have 3
shortened elements on 40/30 and 4 full sized elements for 20-6m.  4 elements
on 17m is a hoot when the band is open.  I was working 9V's the other day
early in the morning while hoping for the BS7 guys to show up on the band.
To be able to do that all in one antenna in a fairly small package is great.
One with multi elements on 40 in a much smaller package then the MonstIR
should be a big hit.  3 ele on 30m would be pretty fun too!

I have two 4ele SteppIRs and one in Montana is having some swr issues.
However I used a "broken" 4 ele SteppIR to grab 3rd place Multi in the 2005
SS phone contest.  Feel free to compare our 20m numbers with just about
anyone else and you will see that we stacked up very well against
competitors with much more aluminum in the sky.

Dang - I've just realized that complexity is evil!  I'm gonna sell my C5
Corvette - I found out it has 5 computers in it at the least!  Progress
